A tunable dual-frequency metamaterial graphene polarization converter in the infrared range is put forward in this paper. The proposed converter is made up of 3 layers—the bottom gold layer, the middle silicon dioxide layer and the upper graphene layer. The simulated results show that the polarization converter can simultaneously work at two resonant frequencies of 36.82 and 41.38 THz. The polarization conversion rates are up to 0.9992 at 36.82 THz and 0.9969 at 41.38 THz under the certain normal condition when Fermi energy is given to 1.0 eV, showing the high efficiency of the polarization converter. Moreover, the converter shows its stable working performance under the change of the incident angle and the geometrical size. Meanwhile, without varying the nanostructure, the resonant frequencies can be flexibly adjusted by controlling the Fermi energy. The superior performance of the proposed graphene polarization converter indicates a broad prospect that a large number of applications such as infrared imaging sensors, modulators, switches, photonic and biochemical sensors, light harvesting, thermal detection and electromagnetic energy converter will apply it.

“…Using micro-and nano-structures with characteristic lengths smaller than or close to the wavelength of incident light [5], it is also possible to achieve special physical properties that traditional materials do not have, such as negative refractive index [6,7], negative magnetic permeability [8], negative dielectric constant [9], etc. Thus, micro-and nano-structure-based materials (including metamaterials) are potentially useful in stealth camouflage [9,10], polarization detection [11], perfect absorber [12], super-lenses [13], nano-heater [14], anti-icing effects [15], and so on.…”

A Dual-Band Guided Laser Absorber Based on Plasmonic Resonance and Fabry-Pérot Resonance

We numerically investigated a dual-band metamaterial absorber based on the combination of plasmonic resonance and Fabry–Pérot (FP) resonance, which can achieve near-unity absorption for guided lasers. The absorber is constructed by a three-layer metal-insulator-metal (MIM) periodic configuration. In each unit cell, there is a gold-silicon cross on a thin silicon layer and a bottom nickel film. Numerical results show that, at normal incidence, the structure strongly absorbs light at wavelengths of 1.064 μm and 10.6 μm, with absorption rates higher than 94%. It is revealed that the two absorption peaks result from FP resonance in the thin silicon layer and plasmonic resonance in the cross, respectively. In addition, the absorber is polarization insensitive and is tolerant to the incident angle. The proposed combination of different resonances has the advantage of easily producing double absorption peaks with very large wavelength differences, and provides a new approach to the design of metamaterial absorbers.

“…The polarizer [1][2][3][4][5] can split the incident light into two mutually orthogonal polarized lights, which plays an important role in the field of terahertz devices [6], infrared telecom [7], information technology [8], information processing [9][10][11], imaging [12][13][14][15], optical storage [16][17][18][19], and polarization detection of light [20][21][22][23]. The conventional polarization separators are usually based on the birefringence of crystal, and the size is generally in the order of millimeter.…”

A T-shaped reflective grating device under the second Bragg angle is proposed for polarizer. This grating device is mainly made of fused silica with T-shaped ridges, which can diffract the energy of the TE-polarized light and the TM-polarized light to the −2nd order and the 0th order with the reflective efficiency of each order more than 95%. Normalized field magnitude distribution and overlap integral are analyzed to explain the physical mechanism and energy exchange. Based on the optimized results, the beam splitter exhibits high efficiency, good extinction ratio and optical properties of the incident bandwidth. Moreover, grating can have longer period for easy fabrication under second Bragg incidence compared to reported Bragg incidence. Therefore, the T-shaped reflective grating device should be useful for the future optical communication industry.
